Method and device for communication

Abstract

The present disclosure discloses a method and a device for communication. The method includes: determining, by the user equipment, a specific uplink-downlink sub-frame configuration when the uplink-downlink sub-frame configuration information is not received by the user equipment during the period; and communicating with a network side equipment by the user equipment during the period based on the specific uplink-downlink sub-frame configuration.
